I primarily develop at home on my Windows machine, but all of my web projects live on a Webfaction-hosted linux machine. To create a smooth deployment process with Grunt that will run my tests on either machine I used the PhantomJS node package.

The trick here is that it can't be copied over with the deployment; it needs to be installed by npm on the target machine to run properly. You can make this happen pretty easily by ensuring it's installed globally on both machines, but still included in the package.json file. Npm is smart enough to not double up the installation when you run npm install from either box.

I am using the same Durandal/Jasmine setup I wrote about here. I am running the phantomjs spec.js file by using this Grunt setup

the cwd parameter is important, since the spec.js file uses path's relative to itself. Everything else is pretty self explanatory. If you want a more complete picture, you can check out my portfolio project as it was at the time this post was written.

I tried doing this with the actual grunt-phantomjs package, but the way it wraps things made it significantly harder to use. Since my spec.js was already fully setup, using PhantomJS directly was just easier.
